CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 369,507, datedSeptember 6, 1887.

Application filed April 14, 1887. Serial No. 234,830. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM DUNKLE, a cltizen of the United States,residing at Linden, in the county of Montgomery and State of Indiana,have invented certain new and useful Improvements in Corn Planters andMarkers; and Ido declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying draw ings, and to letters or figures of referencemarked thereon, which form a part of this specification.

Figure l of the drawings is a representation of a plan view. Fig. 2 is atransverse section on line 3 3 Fig. 1. Fig. 3 is a side elevation,partly in section, taken on the line :0 00, Fig. 1. Fig. 4 is a planview of the rotating dropper. Fig. 5 is a bottom view of the same. Fig.6 is a detail plan view of the droppertube, and Fig. 7 is a verticalsection of the same. Fig. 8 is a detail view of a portion of one of thebeams d and a portion of one of the side beams, a. Fig. 9 is a detailside elevation of the same.

The invention relates to improvements in corn and seed planters; and itconsists in the construction and novel arrangement of parts, hereinafterdescribed, illustrated in the draw-- ings, and pointed out in theappended claims.

Referring to the drawings by letter, A designates the main or wheelframe of the machine.

B designates the axle, and I) b the wheels turning freely thereon.

O is the drivers seat, secured upon uprights rising from the main frame,and c is a shaft pivoted in hearings on the rear rail of the frame A andprovided with the scraper'blades c c, which, by means of the cross-piecec and a suitable handle, 0 standing therefrom within easy reach of thedriver, can be turned on the rims of the wheels to clear them fromadhering earth.

D is the inner frame, having the tongue (I attached to its front portionand provided with the side beams, (1 cl, to which the side beams, a a,of the main frame A are pivoted at d, the pivotal pins d" passingthrough the vertical slots (1. a on the ends of the beams a a, which areoutward from the beams 12, as shown.

circle, and secured upon one of the side beams,

a, of the frame A. The teeth of the said rack are engaged by a detent orpawl, 5 moving on a guide, g, secured to the side of a leverarm, 9,rising from the corresponding end of the shaft F.

g is a hand-lever connecting with said detent by the link-rod g, thedetcut being forced downward into engagement with the rack by the spring5/. By means of the said lever, de tent, and rack and the shaft E andarms f and e, the runner-frame can be set in the wellknown manneron themain frame to make the hereinafter-described runners penetrate more orless deep in the soil.

H is an upright transverse frame secured to the side beams of therunner-frame and having the dropper-tubes, hereinafter described,secured upon its similar lateral extensions, h h, outside of said beams.The vertical arms h 72. of said frame are hollow and slottedlongitudinally and similarly on their outer and inner sides, the shaft Ipassing through said slots h h, and having the hubs i secured to itsends, which hubs are provided with the equi distant radial arms i i.

The shaft I is journaled in boxes J, fitting in the interiors of thevertical arms k and pressed downward by the coiled springs jj above themin said arms.

j j are short coiled springs situated below the boxes J and preventingany jarring action of the springsj.

K is a wheel secured centrally on the shaft I, and having its rim 7cedged, the cross-section thereof being V-shaped.

L L are radial marker-bars, having the feet llstanding at right anglesoutward to their shanks and passing through openings in the lugs Z Z,standing out from the cross-bars Z l,

secured at their ends to adjacentspokes Z of the wheel K. The saidmarker-bars are equal in number to the radial arms on each hub i and arepreferably three. Each bar is pinned to the inner side of the inner lugZ and between the lugs is surrounded by the coiled spring Z", whichgives when the foot of the marker-bar presses on the earth and preventsjar or breakage.

The edged wheel K penetrates in the soil, and, while allowing themarkers to score plainly, prevents the rows from becoming irregular andany lateral displacement should one of the runners strike an obstacle,such as a stone.

M M are the furrow openers or runners, of usual shape and construction,extending from the front transverse bar of the runner-frame to the lowerend of the dropper-tubes N, which are rectangular in cross-section andhave secured to their upper ends the fixed dropperdisks it, providedwith the slots at, through which slot projects the reduced end 0 of thespring-,droppers 0, each of which is pivoted at 0 in the correspondingdropper-tube, and

is pressed upon its pivotal point by the spring 0 secured within thesaid tube in such manner that while its upper edge rests against the oneedge of the slot n its lower edge rests against the opposite side of thedropper-tube. Each spring dropper-plate is as wide as the interior ofthe dropper-tube, so that when in the position described it cuts offcommunication with the part of said tube below.

P l? are the rotating dropper-plates, each having a central circularopening, so as to turn upon a cylindrical projection, 19, risingcentrally from the fixed dropper-disk n. The projection 1) has above itsshoulder 19 a tapped end, 1), to secure upon it the seed-box Q,preferably rectangular, and having its floor q provided with theconcentric slot q, resting on the shoulder 12, with the tapped end 12passing through a central opening in it and engaged above by a nut andwasher to keep the seed-box from turning. Each rotating dropper-disk issituated between the floor of the corresponding seed-box and the fixeddropperdisk, and is provided with the series of equidistant openings R,concentric with its center and registering with the slot q, theequidistant arms 7 standing radially outward from its edge and on itsunder surface, with the curved recesses r concentric with its center andseparated by the transverse bridges 1' The openings, radial arms, andrecesses are equal in number, which number is preferably six.

As the wheel K rotates, the arms t" on the hubs t strike the arms 1" onthe rotating dropper disks and move said disks partially around, movingthe openings R, filled with grain from the seed-box, through the slot q,toward the slots n of the fixed dropper-disks. The said openings R, uponreaching the slot it, allow the grain to fall therethrough upon thespring dropper-plates O, which retain the grain until the next followingbridge, r strikes against its projection o and forces its lower end awayfrom the side of the dropper-tube N against the action of the spring 0so as to allow the grain to fall into the furrow made by the runner. Thegrain has thus two drops one produced by the movement of the rotatingdropper-disk, allowing it to fall on the dropper-plate O, and the otherby the dropperplate being opened from the dropper-tube, as described.The planting of the seed is thus better regulated.

The springs above the boxes of the shaft of the edged wheel allow saidshaft to give, so that when the runner-frame is turned to differentangles on the main frame the depth to which said wheel penetrates thesoil is kept very nearly equal.

Having described this invention, what I claim, and desire to secure byLetters Patent,
